Microwave and millimeter-wave integrated circuits (MMICs) are of increasing im- portance in modern military and commercial wireless communication systems. Current trends are towards low-cost, high-density, multilevel,and multifunctional integration, cover- ingmillimeterand submillimeterwave regions.The integrationofdiverse subfunctions, such as light-wave devices, superconductor circuits, digital circuits and ferrite devices, together with conventional microwave or millimeter-wave devices, circuits and antennas, will allow implementation of large systems on a single chip. Research on advanced device concepts, 3-D interconnects, high-performance packaging methods, advanced CAD-tools, measure- ment and testing techniques, as weil as material and fabrication technologies, are being di- rected to meet these new challenges. Continuing on the series ofsymposia sponsored by the Weber Research Institute of Polytechnic University, an international symposium focusing on the current developments and new research initiatives for the next generation ofmicrowave and millimeter wave inte- grated circuits and systems was held at Brooklyn, New York,during September 11-13, 1996. The symposium was organizedas a3-dayevent,running mostly ina single-session format of regular papers and panel discussions, It was co-sponsored by the Army Research Office, Re- search Triangle Park, NC, in cooperation with the IEEE Microwave Theory and Techniques Society, the IEEE Antennas and Propagation Society, and IEEE Long Island and New York MetropolitanSections.The papers published in this volume are extended versionsofselected papers presented at this symposium.

In 1945, Dr. Ernst Weber founded, and was the first Director of, the Microwave Research Institute (MRI) at Polytechnic University (at that time named the Polytechnic Institute of Brooklyn). MRI gained worldwide recognition in the 50s and 60s for its research in electromagnetic theory, antennas and radiation, network theory and microwave networks, microwave components, and devices. It was also known through its series of 24 topical symposia and the widely distributed hardbound MRI Symposium Proceedings. Rededicated as the Weber Research Institute (WRI) in 1986, the institute currently conducts research in such areas as electromagnetic propagation and antennas, ultrabroadband electromagnetics, pulse power, acoustics, gaseous electronics, plasma physics, solid-state materials, quantum electronics, electromagnetic launchers, and networks. Following MRI tradition, WRI has launched its own series of in-depth topical conferences with published proceedings. Previous conferences in this series were: Directions in Electromagnetic Wave Modeling; October 1990 Ultra-Wideband Short-Pulse Electromagnetics; October, 1992 Ultra-Wideband Short-Pulse Electromagnetics, II; October, 1994 The proceedings of these conferences were also published by Plenum Press. This volume constitutes the proceedings of the fourth WRI International Conference dealing with Guided-Wave Optoelectronics: Device Characterization, Analysis and Design. The conference was held October 26-28, 1994, at the Polytechnic University in Brooklyn, New York, in cooperation with the IEEE Lasers and Electro Optics Society, and with the Optical Society of America.
